Title: 5” GP100 10mm
Post by: Rick R on November 25 2018 09:44:09 AM MST
Just so I'm not the only one suffering from the tribulations:

This would be legal to hunt with where my 3" isn't...

I bought one last month.  My LGS had one, didn't even know this existed.  Ruger still doesn't have it listed on their site.  I was going there to buy the MC in 10MM, and I saw what looked like a Security Six with a 10MM tag.  Sold! Love the classic lines, but I switched out the wood grip for a Hogue fingerless grip.  I've only had it to the range once, but it ran both 10MM and .40S&W with the included moon clips.  Only had one FTF with the .40S&W, but it fired on the next go round.  Bought some of the thicker moonclips from TK Custom.  Hoping to get some time to try them out in a week or two.

Over 2x what I paid for my S&W 610 with 5" barrel 😂
And now it looks like I will be buying a Ruger

Got one recently. Was disappointed with the moon clips that Ruger supplied although no tools are needed ( I do not want to pay $80.00 for 10 for the same copied clips, although they are thicker.) Already one of the clips will not hold a round and you have to hold it on the clip while you place it in the cylinder. Of course none of the clips I have for my 610 can be used on the GP. Contacted Ranch clips and found they had clips that were made for the S&W 646 but would fit the GP. $12.00 for 8 pp and they fit just fine. They  would not fit on the demooning tool I use for my 625 and 610 which is a breeze and removes 2 each time the handles are squeezed but I sanded the center post that the clip sits on and it works fine now.
Like  it but will need to get some grips that "fill-in" the concave portion of the frame that hits between my thumb and finger and that recoil  does not feel good. Will continue to shoot it by placing my "pinkie" under the handle. Got a line on some Pachmayrs as the Hogue grips for Super RH and GP will not fit this Ruger.
All in all, I like it and it seems to like pretty much any loads I  used yesterday-BD, BE, AA7.

Midway has the 646 moo clips for $8.99 (https://www.midwayusa.com/product/1006195348/ranch-full-moon-clip-s-and-w-646-40-s-and-w-6-round-blue-pack-of-8).  I bought two sets for my 10mm GP100 and they work great with both 10mm and .40 S&W.  Also, any GP100 grip will fit any GP100 regardless of caliber.  I replaced the wood grip that came with my Lipsey's GP100 with the Hogue grip that comes with the .44 special GP100.  Zero issues with the fit.

Yea-Was able to remove the grip panel locator (pin or dowel) and now the hogue grips will fit. Very easy to install the stirrup in the bottom of the frame and used
the supplied screw that came with the grips to secure the grips to the frame. Had to use a good bit of force to get that pin out of the frame.

Are you using a CCW de-mooner?

I bought one years ago for my 25-2.  Didn't seem to work with current brass till I dremmeled some off the center post.

Shit, I may have to buy one of these.

From your descriptions.sound like I have the CCW de-mooner. It worked fine for my 610 and 625-6. Had to reduce the diameter of center post so the clips for the S&W 646 would slip over the center post.

Im wanting one of these...

They have been on the radar for a while. Maybe last spring. But I learned they are "approved" for me. ????

Now to allocate the finds in these lean covid times...

Bought one in July, 2020 and I love this 5" GP 100. The cylinder mouths are a little oversized so I'm looking for someone who makes a 175grain SWC lead with a .403 diameter bullet. Best group so far is 2.25" at 22 yds with Selleir and Balloit 180 10mms.

I can assume that you dont cast for yourself then?

I picked up a .401, .402 & .403 in my first order to NOE for there then new push thru bullet sizer die.

Some bullet makers offer "AS CAST" bullets. So you could get those and the sizer and size your own. Using either powder Coat or pan or tumble lubes.

Why?  You want the cylinder mouths to be larger than the bullet.  The last thing you want is the cylinder mouths to size the bullet down.  A bullet sized .401 will be sized down by the barrel and provide a seal and a tight foit to engage the rifling.  The usual problem with Ruger revolvers is the cylinder throats are to tight.  My GP 1-- in 357mag had cylinders moiths so tight a .356 bullet would not pass through them.  I had the mouths openned up to .358 to allow my bullets to pass through the cylinders without being sized down.

Zeke38:
Check out PENN Bullets  https://www.pennbullets.com/index.html (https://www.pennbullets.com/index.html). He will size 10mm bullets to .403; however, the 10mm GP tends to have tight chambers (bad combination) therefore loading .403 bullets may create a cartridge that won't slip into the chamber easily (but try some out and see if they work). .403 throats are not unusual in the GP, mine has them too. The factory says that their tolerance is from .400 to .403, therefore they won't replace your cylinder (already tried). That being said, I have found that polymer coated bullets protect lead bullets from the damage of the hot gases passing as the bullets exits the throat, I put over 500 rounds of lead through mine without any barrel leading issues.

robertbank:
You are right, you do want your throats to be larger than the bullet, but only by .0005". The bullets should pass through the throats with a little thumb pressure, but if they fall through hot gases will rush past the bullet on the way out of the throat, vaporize the lead and then deposit this lead in the first 1"-1½" of the barrel. .403 is much too large for a .401 bullet. Of course, if you only shoot jacketed or plated bullets (or polymer coated) over sized throats are not as much of a problem. Shooting bullets that are too large for the throats will eventually beat your cylinder against the yoke and your endshake will increase - a much bigger problem than barrel leading.

I may add a Ruger GP 100, 10 mm to my 10mm collection,never thought about it before now.

Been wanting one for some time now
There's something about that Blued Finish that draws me to it, way more than to the Stainless Match Champion
